Daniel,
I got some motors for my Polaris (Celestron) mount from Astromeccanica in Italy.
These were stepper motors with a hand controller. It has a port to connect to an autoguider and can connect via a serial port to most of the common astro programs, I've used it with Starry Nights.
I don't have any details as I'm at work but if you want contacts, pictures etc, let me know and I'll take care of it when I get home.
(found the link to the site. It's now at
microgiga - the astromeccanica is for the optical side of things,
Forgot to ask, how's your italian
)
